and their photocatalytic activity for methyl orange LI Ai-chang, WANG Li-na, FAN Hong-xian (Faculty of Chemistry and Material Science, Langfang Teachers College, Langfang 065000, China) Abstract: Silver-modified.... The surface morphology, chemical composition and structure of the film were characterized by SEM and XRD, and its photocatalytic property were evaluated with methyl orange as model compound......
in electrolyte solution containing 5×10-4 mol/L ethyl xanthate, and the effect of potential on the composition and characteristics of surface film were studied by cyclic voltammetry (CV), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). The adsorption of xanthate (X-) occurred on the mineral surface at open-circuit potential (OCP). In the potential range from -0.11......

), Harbin 150090, China)Abstract:A batch experiment was conducted to investigate the adsorption of an acid dye (Acid Orange 51) and a basic dye (Safranine) from aqueous solutions by the sludge-based activated carbon (SBAC). The results show that the adsorption of Acid Orange 51 decreases at high pH values, whereas the uptake of Safranine is higher in neutral and alkaline solutions than that in acidic......
